Claims.

' My invention relates to the art of winding and reeling and to the method whereby the coil wire of a coil unit may be machine-wound upon the coil form when the latter is mounted upon the leg of a closed magnetic core of a transformerdevice or the like.

I am aware that various attempts have been made to provide means and methods for machinewinding a coil upon a transformer or the like, examples being illustrated in United States Patents Nos. 397,705 and 2,305,999. However, while these attempts may have, to a limited degree, advanced the art with respect to the hand-winding method, they still present many difficultie and disadvantages for instance, the manner of constructing the coil form, means of holding'the form sections or components together, means of effecting a driving relation between the form and a driving device, and providing the form with a proper bearing surface for engagement with the leg of the transformer core. 7

My invention overcomes the foregoing difiiculties and presents numerous advantages over the art, it being one of the principal objects thereof to provide a coil form so constructed and arranged whereby the same may be expeditiously mounted upon the leg of a closed magnetic core of a transformer-device or the like and in a manner whereby said form may be rotated about the leg to effect winding of the coil wire thereon.

Another object of my invention is to provide a form of the foregoing described character having complementary components separable to effect mounting of the form upon the leg of a closed core.

. A further object of my invention is to provide a form of the foregoing described character ing of the components during rotation.

A still further object of my invention is to provide a coil form of the foregoing described character equipped with means for securing the components in relative fixation when assembledand mounted upon the core.

A special object of my invention is to provide a coil form of the foregoing described character provided with means for effecting a positive driving connection with a driving device whereby the cludes means for calculating the number of turns of wire fed upon the form.

An important object of my invention is to provide a form of the foregoing described character equipped with means for precluding rotation of equipped with means for precluding relative shiftprovided with the usual outer legs ll.

the form upon termination of the wire-winding operation.

.Another important object of my invention is to provide a method whereby coil forms may be readily assembled upon the leg of a closed magnetic core and coil wire machine-wound thereon in an expeditious manner.

A further important object of my invention is to provide a form of the foregoing described character which is simple in construction, eiiicient in use, economicalin manufacture and which lends itself to quick assembly and high productivity.

With the above and other objects in view, as will hereinafter appear, the invention consists in the combination and arrangement of parts or components hereinafter set forth and illustrated in the accompanying drawings from which the.

several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Fig. 1 is a side elevation of a winding organization disposed in operative position with the core of a transformer-device.

Fig. 2 is a side view, partly in section, of the form.

Fig. 3 is a side elevation of one of th form components.

. Fig. 4 is a sectional view taken on the line 4-4 of Fig. 1.

Fig.- 5 is a perspective view of one of the wedges.

In practicing my invention, as illustrated in the drawings, 1 provide a oil-winding organization 5 comprising a reel 6 containing a supply of coil wire I, said organization 5 being equipped with a guide 8 for guiding the wire I onto a form or spool 9, and with the guide 8 constituting a part of a' traversing mechanism Ill. The traversing mechanism In is connected and operated by means of a motor II or other suitable source of power, said motor being equipped with the usual drive shaft I2 on which is mounted a drive wheel l3 having a serrated periphery or treated surface l4. As illustrated in Figs. 1 and 4 0f the drawings, the form 9 is mounted upon the center leg l5 of the closed core iii of a transformer-device or the like, said core l6 being of the shell type and Inasmuch as the core is of ordinary construction and forms no part of the present invention per se, a more detailed description of same is not believed warranted.

The coil form or spool 9 is fashioned with a cylindrical portion [8 having ends provided with flanges l9 between which the coil wire is wound upon the portion I8 to form a coil unit. The form 9 comprises, in the present instance, a pair of complementary or replica components 20 having abutting faces 2| extending spirally or abaxially throughout the length of the form, and which faces are provided with dentents 22 and adjacent detent receiving slots 23 constituting interlocking means with the adjacent component for precluding relative shifting of the components 20. The circumferential faces of the flanges I! are provided with serrations constituting tread surfaces 24 wherein one of said surfaces is disposed in engagement with the drive wheel 13 whereby to effect a positive driving connection between the wheel 13 and the flange l9 during the winding of the wire upon the cylindrical portion. The tread surface 24 of the other flange is of the form 9 is disposed in driving relation with a driven wheel 25 comprising a part of a calculating device 25, the latter being of ordinary construction and operating to denote the number of turns of the wire upon the form 8.

When assembled upon the leg l5, the components or sections 20 of the form 3 are secured and maintained thereon by means of a strip of adhesive tape 21 or the like applied about the cylindrical portion [8 and upon which the wire 1 is wound. The form' 9 is fashioned with a bore 28 through which the leg l extends, the peripheral face of the bore being disposed in spaciality with the faces of the leg. The face, adjacent the ends of the form, is provided with bearings 29, each having a running fit about the center leg l5. By extending the abutting faces 2| spirally, smooth rotation of the bearings upon the center leg and winding of the wire upon the form is effected and without the usual socalled clicking" noise. The center leg I5 is of a cruciform configuration in cross section and with the branches defining channels 3| interjacent said branches. The peripheral faces of the bearings are provided with longitudinal slots 32 in which are inserted cuneiform members or wedges 33 which extend into registering channels 3| and thus preclude rotation of the form about the center leg upon termination of thewire-winding operation. Thus it will be apparent that the channels 3|, slots 32 and members 33 constitute locking means for maintaining the form against rotation when said members 33 are applied thereto.

In operation, the components of the form 9 are assembled about the center leg l5 and secured in the assembled relation by applying the strip of adhesive tape 21 about the cylindrical portion I8. When the form is thus mounted upon the center leg, the core is adjusted with respect to the winding organization and in a manner to effect engagement of the drive and driven wheels l3 and 25 with the tread surfaces of the flanges of the core thereby effecting rotation of the form by the winding organization until the desired number of turns of the wire is obtained uponthe form. Upon completion of the winding operation, the core is removed together with the core unit thus formed thereby establishing the core form as an integrant of the core. While in the present instance, the form is constructed of an insulating plastic material, it is to be understood that any other suitable material may be utilized when desired. I

It is also to be understood that the language used herein and in the claims is intended to cover all the generic and specific features of the invention' herein described, and 'all statements of the scope or. the invention which, as a matter of language, may besaid to fall therebetween.

Without further elaboration the foregoing will so fully explain the invention that others may.

by applying current knowledge, readily adapt, the same for use under various conditions of service. Moreover, it is not indispensable that all the feaperipheral ascaovv tures of the invention be used coniointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined to the herein described use therefore as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described as the same is only illustrative of the principles of operation, which are capable of extended application in various forms, and the invention comprehends all construction within the scope of the appended claims.
